To allwhomitmaycomem;

vBe it known that I, SIMONl COOPER, a citizen of the United States,yresiding at Brooklyn, in the county of'Kings and State of New York,have invented 'certain new and useful Improvements in Sealing vMachines,of which the following is a specification.

The subject of the present invention is a machine for applying sealingwires to pails and other containers.

The objects of the invention are to provide a simple, practical andeiiicient machine for the purpose stated.

In the accomplishment of these objects, I employ in combination withmeans for supporting and holding the pails, mechanism for severing thesealing wires into lengths and for pointing the ends of such lengthstowards the supported pail and for then driving such ends into the bodyof the pail. The invention embodies also other features such as meansfor upsetting or securing the ends of the inserted wires at the insideof the pail, allof which will appear as the specication proceeds.

In the drawings accompanying this vspeciication, I have disclosed theinvention embodied in a concrete, practical form ybut wish it understoodthat the structure may be modied in various respects without departurefrom the true spirit and scope of the invention, as defined in theappended claims. I would also have it understood that the terms which I.have employed are used in a descriptive rather than in a limitingsense, .except as may be required by the prior art.

In the drawings referred to, Figure 1 is a top plan view of the machinewith parts broken away and other parts shown in section.

Figure 2 is a vertical sectional view of the machine taken.substantially on the of the line 2--2 of Figure 1. v

Figure 3 is an enlarged and broken top plan view of one of the wirebending andvv riving devices.

' sealing wires.

The machine embodies, first, a holder or support for the pail beingoperated upon. This holderI have shown in the form of a head 15 (Figure2) againstwliich the pail 16 is pressed by a plunger head 17. A pedallever 19 is operatively connected to the plunger head 17 by,a shaft 18and surrounding this shaft 18 isa spring 18 which yleldingly holds theplunger head 17 in a raised position. v'

The wire from which the seals are made is indicated at 20, two separatelengths of such wire being shown, each length being fed into the machineby a Wire feeding device, embodying in each instance a carriage 21sliding on the guides 22, said. carriage carrying relatively xed andmovable wire gr1pping jaws 23 and 24, the latter being carried by abell-crank lever 25 pivoted on the carriage at 26 and connected with oneend of a link 27 whose other end is connected with a lever 28, which inturn is con- `View of lthe head portion of the machine, v

understood that the wire feeding device at the. rright in'Figure 1 maybe operated by means similar to that disclosed for the feeder at; theleft side ofthe machine. lTheA wires r`are advanced by these feedingdevices nol through guides 32 into position to be ktaken 'Y by thejwirebending and y driving devices Fourfof the wire bending and drivingdevicesy arel provided in the y v c machine illus- 9,5` trated,` grouped`radially about the pailfl holder and operating in pairs to bend anddrive into the pail the opposite ends of the two lengths of wire cutfrom the two sources of wire supply. Referring particularl to Figures 1,3 and 4, it will be seen that t lese devices comprise in each instance,a slide 33 working in guides 34, said slides reciprocating substantiallyradially of the pailholder and carrying at the inner end thereof adevice for gripping and bending the wire. This device, is shown as aixed blo-:lr or former 35 on the lower face of the slide and an arcuatebending arm 36 carried by the lower end of the shaft 37 and arranged tobend the end portion of the wirey about the stationary former. rlhisbender shaft has secured to its upper end a .lever or arm 38 to whichone end of a toggle is pivoted at 39. rllhe two levers, constituting thetoggle are designated 4() and 41, the rst of these being pivoted to thebender arm at 39 and the second being pivoted to the rearward end of theslide at 42. These toggles -are operated, in each instance, by a link 43pivoted at one end to the joint of the toggle at 44 and connected at itsopposite end with a rocker arm 45. lhese rocker arms are secured on theupper ends of the rock shafts 46 andr47. Rock shafts 46, in the machineillustrated, f receive motion from the cams 47 on the cam shaft 31through the medium of levers 48 carrying rollers 49 engaging the groovesin said cams and rock shafts 47 receive their motion from the rockshafts 46 through the medium of the intermeshing gear segments 50 and 51on their respective shafts. From this it will be apparent that the fourtoggles are made and broken substantially simultaneously. Adjustablestops are shown provided at 52 to prevent movement of the toggles pastthecenters. ln Figures 3 and 4 the toggle is shown in the brokencondition, in which the bending jaw is thrown open and it. will beapparent that as the toggle is made or straightened the jaw ywilloperate to bend the end of the wire about the former, in the mannerindicated, so that the projecting point of the -wire will standsubstantially radial with respect to the center of the pail onthepailsupport. Also in these views there is shown a guiding member 53, fordirecting the Wire into the bight of the bending jaw.

v'llhe wires are severed in proper lengths by means consisting in thepresent disclosure of the wire cutter blades 54 (Figure 1) carried byrock shaft 55 which are operated by arms 56 connected by links 57(Figure 2) withy the arms 58 of bell-crank levers pivoted at 59 andwhoseother arms 60.are actu-4 ated by suitable cams on the cam shattSl. Thecutters described are constructed to point the wire ends in the act ofsevering the wire.

After the ends ont a length of wire have incarico been caught by thebending devices of two of the adjacent slides (those at the right or atthe lett in Figure 1) and bent inward toward the pail, as shown, the twoslides are bodily advanced to drive the inwardly directedv points of thewire into the body of the pail. The means for thus advancing the slides:comprises the arms 61 pivotally mounted on the lower endsof rock shafts46 and 47 connected at one end by the links 62 with the slides, whilethe opposite end of each of the arms 61 is connected to the links 63. f

The movement ot these slides is suicient to drive the inwardly bent endsof the wire in through the wall of the pail, as indicated in Figure 8.The projecting ends of the driven wires are then curled over, asindicated at 64 in Figure 9, after which the curled or bent over ends ofthe wire are flattened down and driven back into the wall of the pail,as indicated 'at 65' in Figure 10.

The means for curling or bending over the projecting ends of the wiresare illustrated-more fully yin Figures 5, 6 and 7 and consist in eachinstance ot a pair of spaced abutments or pins 66 and 67 between whichthe end of the wire is driven, the rst of said pins being concentricwith the shaft 68 which carries it and the second in is eccentricthereto so that in the rotation of said shaft the eccentric pin willwrap the projecting end of the wire about the concentric pinsubstantially as indicated in Figure 7 Four of these wire curlingdevices are provided in the present disclosure, the same belng mountedin guides 69 on the head of themachine and being driven. rotarily bypinions 70 on the upper ends of the curling shafts 68 in mesh with agear 71 on the central shaft 72.

The shaft 7 2 is oscillated, in -theLmachine illustrated, from a cam 73oncam shaft 31 through the medium ot a cam actuated lever 74 which issecured to the lower end of a.

after the completion of the curling operation (Figure 7), the furtherrotary movement ot t e central shaft 72 will cause'the curlers to beretracted from the pail. The gear 71 may be of interrupted or mutilatedconstruction to permit of this further rotary movement ot the centralshaft for the retraction ot the curlers, the curlers then beingwithdrawn without rotary movement.

lill@ The pail is centered and supported at the top, in the machineshown, by a frame or head 82 on the lower endrof shaft 72 and which fitsinto the upper end of the pail as the same is raised by plunger head 17.This supporting head is also here utilized for iattening down theprojecting wire ends, it being shown as provided for the purpose, withthe anvil or presser shoulders 83 which,

when the Wire ends are driven inward stand to one side of such ends(Figure 6) and which in the rotation of the shaft 72 are caused tooverride the curled; wire ends (Figure 7) to flatten the same down anddrive the points back into the wall of the pail, as shown in Figure 10.

The present machine is controlled so as to stop after the performance ofa complete cycle of operations, a one-revolution clutch being providedfor this purpose, as indicated at 84 in Figure 1 (right hand end ofligure), said clutch being mounted on the drive shaft 85 which carriesat its opposite end the drive pulley 86. This clutch is controlled by alever 87 (Figure 2) pivoted at 88 and havingvan arm 89 carrying a roll90 in engagementwith cam 91 on the cam shaft 3l. Clutch lever 8T is alsoshown provided with an upstanding arm 92 to which there is connected acontrol rod 93.

In operating the machine, the foot pedal 19 is rst. depressed to lowerthe presser head 17. After placing a pail on said presser head. thepedal is released and the pail is thereupon raised by the presser headinto' engagement with the fixed head 15, it being centered thereon bythe anvil-carrying mem ber 82. The handle rod 93 is thereupon actuatedto trip the one-revolution clutch. Motion from the drive shaft 85 isthereupon imparted to cam shaft 31 through the medium of gears 94 and95. The wire feeding devices are thereupon caused to advance, and tofeed the proper lengt-hs of wire into the grip of the wire benders onthe slides.

The Wire cutters thereupon operate to sever the predetermined lengths ofwire and to pointthe ends thus severed. The wire benders then operate toturn the ends of the cut wires inwardly toward the center of the pail.as shown in Figure 1, after which the slides advance and drive the endsof the wire in through the wall of the pail, as in Figure 8. The wirecurlers then operate, as shown in Figures 6 and 7. to curl the inwardlyprojecting ends of the wires. after which the curlers are retracted andthe anvils rotate to flatten down the curled ends of the wire. drivingthe points of the wires into the material 'of the pail. as in Figure 10.The ends of the wires are thus firmly anchored in the material of thepail. leaving loops or stretches 96 of wire at the opposite sides of thepail which can be turned up over the pail cover, as indicated in Figure12, and then twisted, as at 97, to secure and j cutter, wire bendingdevices arranged to receive the cut length 0f Wire and to bend theopposite ends of the 'same radially toward a pail on the p ail-holdingdevice the termi- 'nal ends of said wire projectingnbeyond the bendingdevices and means for advancing the bending devices for driving saidbent ends of the cut Wire into the wall of the pail thus held.
